2 3, but with ythe upper pair ofhandles` in their outsiwunvg, extendedposition and resting upon a oor. Fig. 5 is a side, elevation showingA a`pair; ofbarrows `being used by two menin the transportation ofrnechan-vdise up a stairway. L

Referring in detailto theydrawivngs, the improved bar row therein showncomprises an elongated substantially rectangular open frame' 10 made upof 'twin"si`d'e, pieces 11 which at one end of the frame, have deectedend portions which afford, wheelbarrow-like handle ymembers 12. Saidtwin side pieces 1,1. are shown in Fig,` 21 as i Y tubes, square incross section. At the end thereof. op'-A One object of this. inventionisy .to provide a type of n barrow ory truck so` constructed that apair. of them can have a trunk or like article strapped into` placebetween them, so that, when carried upor down stairs by two persons intandem fashion, the uppermostv person; can grasp the handle means of onebarrowv and the person inthe rear can support. with-v both vshouldersand hands,

the handle means of the other barrow, and thusI con'- venientlytransport a trunk or other largearticle, for example a refrigerator, upor down a flight of stairs.

A more specic object is tov provide an' improved latch ingv means formaintaining the aforesaid-- shoulder supportable handles in aretract-ed, position, when not in use; and to provide for adjustingvthe.y latter handles at various distances apart to accommodate, betweenthem, the different sized necks of persons usingthe device.

Still anothery object is to provide improved combined mounting andlatching meansY for swingably attachingand holding retracted certain.ofl the handle members of the barrow and at the Sametime enhancing theaccessibilityv thereof. Y

Yet a further object of the invention is to provide means for adjustingthe shoulder supportable handles at Various inclinations with regard tothe hand graspable handles to accommodate the stature of differentindividuals wherein the weight of the article. being carried can be moreevenly distributed between the shoulders and the hands of the personcarrying the greater-portion of the load.

This application is a continuation in .part of my copending applicationtiled December i4, 1951*, Serial? No. 261,700, now abandoned. l

Other objects, advantages and features of invention will hereinafterappear.

Referring tothe accompanying drawings, illustrative of a preferred,reduced to practice. embodiment of the invention,

Fig. 1 is a front elevation of the device.

Fig. 2 is a fragmentary, rear perspectiveview on a larger scale of thetwinA handle carrying and locking means.' l

Fig. 3 is a side elevation of the device with its upper pair of handlesin a folded or retracted condition, and its lower pair of handles intheir outswung, extended position, in which position they are in use tomaintain the device in an upst'anding position, ready to be loaded.

Fig. 4 is a side elevation of the device similar to Fig;

posite .to said wheelbarrow-like handle members said frame is providedAwith a horizontal basal 'member 13 which is of an inverted T in. crosssection thus provid.- ing it. with fan attaching 'ange. 14 and shelfjanges. 1.5J and 15a, the latter ilange affording` a baggage support.

In its midlength portion the frame 10 Carries a channel shapedcrosspiece 17 which unites and braces its side pieces 1.1. Thiscrosspiece, viewing the barrow in its operative position, hasy its4flange portions 1.8 and 19 directed rearwardly from, its web 20.. A.shaft 2.1 (see Fig, 2), located between and extending parallelto saidflange portions, bridges. the space. between the aforesaid tubular sidepieces, 11a. The midlength port-ion of said shaft 21 is containedfriction tight within a sleeve 23 which; is secured to the web. 20 byaweld 2311-1 'The general structure. of the4 frame. 10.A is` completedby atrans.` verse, brace bar 22 which is located between the, aforesaidcrosspiece 17 and. the. handle4 carrying endof the A medial handle,vforming bar 25 is slidably andfswingably connectedwith each end.portion. of the. aforesaid shaft 21,I said handle forming barsswinging.between two.k positions, in one of which they are directed toward thebasal end of the barrow and in the other. of which they project atsubstantially a right-angle. to the length of the barrow. The swing ofsaid handles 25` toward` the basal end of the barrow is. limited by`the. innerend portions `of said. handles coming intol contact with. theweb 20 of the crosspiece 1,7, saidA handles,- are furnished with stoplugs 26 which engage the outer edge. ofthe flange 18 to limit the swingof said; handles` away from their basal directed position.

The preferred way: of swingably and.A slidably mounting said handles 25is well shown in Fig. 2 where each handle is shown carried by thev outerend of asleeve 27 slidably and turnably carried by the shaft, 21. Aspring 28, coiled around each end portion ofy said shaft,

opposes outward movement ofrtheadjacent sleevev whew ever the adjacenthandle 25 is moved outwardlyfar enough to be swung beyond an arcuatelock-ing shoulder 29 (see- `Eig. 2), provided for it in the adjacent,coped out, end portion of the ange i9, said spring therefore functioningyieldably to hold said-'handle in its inswun-g position, there being anarcuate seat 29aV inwardiy of said shoulder, in which saidhandle 25seats when4 in its inswung position.

As well shown in Fig. 5, the aforesaidv handle members 25 are at timesshoulder supportable. in order better to adapt them for thus functioningthe aforesaid crosspiece flange 1S. is provided with. a Series. ofrectangular cut outs or recesses 31y which are progressively cut Varyingdepths. into the outer edge of said flange, one series near each side ofthe barrow frame.. 10. These recesses are sufficiently deep to allowthe. handle. form@ ing bars 25 to swing outwardly to acompletely/rightangular position, as well as varyingl inclinationstherebe? yond, when their lugs 26 Contact the bottom of said recesses,The aforesaid sleeve 23 limits. the sliding movements of the sleeves 27toward the midwidth of the frame v The already mentioned basal member 13of the frame carries, in an underlying, attached relation to each endportion of its shelf anges 15, 15a, a mounting plate 35 which swingablycarries a conventional castor wheel 36.

Describing in further detail the horizontal basal member 13, theattaching flange 14 is coped out adjacent itsj top edge at each cornerto provide for rearwardly bending between the side pieces 11 a flange 3Sto co-operate with the shelf flange 15 to provide an enclosure in whichto retractedly mount the handA grippable handles 39 and 40.

For the purpose of swingably mounting said handles 3 and 40, widelyspaced apart pivot pins 41 and 42 are respectively provided each havingone end secured to the ange 38 and the other end secured to the shelfflange 15, so that said pins bridge the space between said flanges.Handle 39 is attached toa sleeve 43 surrounding the pin 41 with aworking tit and filling in the vertical distance between the ilange 3Sand the flange 15. Handle 40 also is attached to a sleeve 44 but doesnot completely till inthe vertical distance between the flange 38 andthe tlange'lS. The portion of the sleeve 4d between the upper side ofthe handle 40 and flange 3S is reduced to form a stub sleeve portion 45in order that when said handle 4t) is extended its entire sleevedportion may be slid upwardly until the top of the stub sleeve portion 45abuts the under side of the ange 38. When this is done the pair ofhandles 39 and 40 lie in the same horizontal plane.

A latching means 46 is welded to the attaching flange 14 and extendsrearwardly therefrom at a right angle, said latching means havingdepressions in its upper and lower side edges into which said handlesare nested when in their inswung positions, there being sufficientclearance between the sleeves of the handles and the pins on which theyare pivotally mounted to provide for a slight rocking so that eachhandle can override the locking shoulders carried by the outer end ofthe latch 46 incident to their seating in the aforesaid depressions.

Fig. illustrates the use of two of the barrow frames 10 as a means forenabling two persons conveniently to carry a heavy piece of baggage up astairway. This baggage is shown interposed between the front sides oftwo of the barrow frames with cushioned sides of said frames clampedthereagainst by an upper cinch strap 46b and a lower cinch strap 47, theoutswung shoulder supportable handle of each barrow being directedoutwardly with those in the left hand portion of the view resting uponthe shoulders of the person at the rear and the outswung handles of theother barrow grasped by the hands of the foremost of the two personsshown. The frame is shown provided with ripper loops 46a for said strap4611, and the lower loops 47a for the strap 47.
